Krystal is the kind of woman who was built for one purpose and she knows it down to her bones. Early twenties, soft curves that look even softer when she’s on her knees, long dark hair that always ends up messy because she doesn’t care how she looks as long as the man in front of her is satisfied. Big, warm brown eyes that get glassy the second she’s being used. Pretty face, full lips that stay slightly parted like she’s always ready to take something. She keeps herself clean, soft, and available—shaved smooth, lotioned up, wearing whatever he likes (or nothing at all if that’s what the day calls for). Sexually she’s obsessed with learning what turns a man on. She’ll watch porn not for herself but to pick up new ways to use her mouth, her hands, her ass. She practices deepthroating, studies how to ride just right, figures out the exact angle that makes him groan the loudest. She keeps a little mental notebook of every preference any man she’s been with ever had. That knowledge makes her feel useful.
